minidiag2

minidiag2 is a DaimlerChrysler Powersystemsdiagnostic and parameter setting aid. It can be used separately or to complement Star Diagnose®

products.

minidiag2 is available in three versions:

Version A = successor unit for “minidiag1” with diagnostics texts.

Part no.: 0001530918Version B = incl. PC program for transferring

description files and parameter blocks.Part no.: 0001531018Version C = with authorization to influence statutory

speed restrictions. In this case, thestatutory regulations as under ECE-R 89,Part I, Section 5.1.2.2 are to be observed.

1.1. SymbolsThe following notes are marked with differentsymbols.

1.3. Proper and intended usageThe minidiag2 diagnostics device is solely in-tended for the contractually defined applicationpurpose. Any other use, or one in addition tothis, is not deemed to be proper and intendedusage.DaimlerChrysler cannot be held responsible forany consequential damage resulting from such action. The previous minidiag2 operatinginstructions are to be adhered to.

1.4. Personnel requirementsParameter settings may only be performed byrelevantly trained or DaimlerChrysler trainedpersonnel as well as skilled personnel inDaimlerChrysler authorized workshops.

1.5. Conversions and modifications to minidiag2Arbitrary modifications to minidiag2 may compromise the functionality and safety of thedevice. DaimlerChrysler cannot be heldresponsible for any damage resulting from such action.

1.6. Organizational measuresThe operating instructions should be handedover along with the minidiag2 diagnosticdevice to the personnel assigned to operate itand should be kept close at hand.The operating instructions are to be augmentedby the generally valid, country-specific, statu-tory and miscellaneous regulations pertainingto accident prevention and environmentalprotection.

�!

!All notes which serve to ease bothunderstanding and working with theminidiag2 are highlighted in blue.

This symbol is used for all safety notes,which if ignored result primarily in a risk of material and functional damage.

Risk of injury!This symbol is used for all safety notes,which if ignored may result in immediatedanger of injury or death.

�! Danger of accident and death!The minidiag2 diagnostics device can beused to influence safety-relevant con-figurations on the engine and vehicle (e.g. accelerator pedal analysis, control for engine brake etc.).Improper editing of parameters may signi-ficantly affect the characteristics of theengine or vehicle. This in turn may causedamage to people and property.

1.2. General


General Connection

The minidiag2 diagnostics device enables the following operations to be performed onMercedes-Benz ecu:� programming of accelerator pedal

(see page 16),� parameter setting (see page 18),� reading out actual values (see page 26),� reading out/deleting fault code memory

(see page 30).

All ECUs are subject to constant advanced de-velopment. Please appreciate that for this rea-son we reserve the right to make alterations.Therefore, all details, illustrations and specifi-cations contained in these operating instruc-tions cannot be called on to press claims.

3.1. Connection to diagnostic socket

The ignition must be switched offwhen connecting!

� Use an appropriate cable (see illustration).

Safety

1.7. Mercedes-Benz OEM partsMercedes-Benz OEM Parts are subject to themost stringent of quality inspections and serveto guarantee the best possible functionality,safety and value retention. Each component isspecifically designed, manufactured, selectedand approved for DaimlerChrysler. For this reason, we cannot accept any responsibilityfor consequential damage as a result of usingparts and accessories which do not comply withsuch requirements. In Germany and in severalother countries specific components such as, forexample, safety parts are only approved for in-stallation and conversion when they correspondwith valid statutory regulations.This precondition is always fulfilled byMercedes-Benz OEM parts.In those instances where other parts are usedthat have not been tested and approved byDaimlerChrysler this may – even where in indi-vidual cases an inspection or authorizationexists – lead to an inability to assess or guaranteesuch parts in spite of current market monitoring.Warranty claims may therefore be unilaterallyrestricted by DaimlerChrysler.

1.8. Operating conditionsObserve the following list of operating conditions in order to avoid any damage to the device and components.

� The device may not be stored or operated in locations that exhibit a high degree of exposure to dust or high air humidity.

� Storage temperature may not be in excess of 80°C.

� The operating temperature range lies between0°C and 50°C. Deviating temperatures may compromise the functionality of theelectronic components.

� The device is to be kept dry. If fluid pene-trates the inside of the device, the electroniccircuits will be corroded – this can then lead to a malfunctioning of the device.

� The device may not be opened. The warrantyis rendered null and void if the device isopened. Improper treatment may result indamage occurring.

� Do not drop, push or hit the device. Suchaction could break the sensitive PCBs withinthe device. This could cause the device tomalfunction.

� Do not use aggressive chemicals, solutions orpowerful cleaning agents to clean the mini-diag2. Use a soft cloth dampened with a mildsoap solution only to wipe down the device.

� The device is designed as a diagnostic unitand is not intended for continuous operation.

� Warranty claims will not be accepted for anyfaults which are the consequence of improperoperation, faulty or negligent treatment orhandling.

Faulty devices are to be returned to the address below within the warranty period (6 months as from DaimlerChrysler date of dispatch):DaimlerChrysler AGPowersystemsSVA Department 70567 StuttgartGermany

4.7. Programming accelerator pedalAccelerator pedal contacts (idle throttle, full throt-tle) are not assigned any constant signal values.For this reason, it is necessary to perform a one-time programming of the accelerator pedal on thevehicle ecu.This procedure enters the accelerator pedal contactsin the ecu’s permanent memory. When an accelera-tor pedal or ecu is exchanged the programmingroutine has to be repeated.� The accelerator pedal must be in the idle position� Run ecu search routine (see page 13)� Cursor on vehicle ecu (e.g. ADM or FMR)

5.2. InstallationThe minidiag2 assistant software is available via:� the Internet by e-mail or� on data carrier (diskettes/CD-ROM)

In order for the minidiag2 assistant software to be used, it must be installed on your PC.The system requirements for this are as follows:� Microsoft® Windows™ 3.1 or higher� main memory (RAM) of at least 8 MB� free hard disk capacity of at least 10 MB

5.5. Transferring files to minidiag2Step 1: connect minidiag2 to the PC (connecting cable,see page 8) and then set up the voltage supply.The minidiag2 display now adopts one of threepossible states:

a) main menu is displayed:� Cursor on “3 PC communication”,

confirm by pressing “OK”

The device is ready for communication.� Continue with Step 2

b) Communication modeThe data are not completely loaded and the minidiag2 is then automatically setto communication mode.

� Continue with Step 2

c) empty displayThe operating system has not been fullyloaded or overwritten, and must therefore be transferred again.

Step 8: confirm the following message by clicking on “OK”:

successful data transfer message

“updating” window

The minidiag2 operating program is compared with the PC operating program and updated.

The entire data memory in the minidiag2 is deleted.All parameter blocks and description files are transferred to the minidiag2. With this the data transfer process is completed.

The minidiag2 display then shows the mainmenu and is ready for other applications.

Step 4: click on “communication settings”.New window: “COM settings”Step 5: click on interface (“COM Port”), to which the minidiag2 is connected.

The baud rate cannot be changed!
